I own and compete with a JP LRP-07, so I can speak of what I think about it. I've personally never heard of the LWRC REPR so I can not judge it.
I picked up a JP LRP-07 this year and am absolutely impressed with. I actually got to go inside the JP shop and see them build the rifles. The quality of workmanship put into their rifles is impressive and you will notice it the moment you put your hands on one of their rifles.
I got the rifle about three before attending the Ozarks 3-Gun match. I only had enough time to fire a few rounds to get the rifle sighted in with iron sights, tune the adjustable gas block for my ammo, and get familiar with the rifle. During the match, I was absolutely amazed with my JP LRP-07. I found myself engaging close targets slow at first because I was used to the 308's longer recovery time from the heavy recoil on my other rifles. As I took shot after shot, I progressively sped up as I realized that the recoil was very manageable and I could engage the targets faster than I ever had with my other rifles. The JP LRP-07’s low-mass bolt and low-mass buffer working with the adjustable gas block made it handle the recoil well.
Consider this...there are a lot of competitors out there using a rifle with some sort of JP component in it. That in itself says a lot about the JP products.

How much does the spring compress? How often should it be changed?
It'll probably compress to about 2-3 inches, depending on the overall lenght of the spring relaxed and the number of coils.
My Benelli Supernova has a 24" barrel and a Nordic Comp mag tube extension that is flushed with the barrel. I'd say that my overall lenght of my tube is around 24". The Nordic Comp spring I use is cut to 38" long when completely relaxed, which leaves about 14" hanging out of the mag tube with the end-cap removed. Now a live "2&3/4" shell is actually just a little over 2&1/4" in lenght. Lining up nine rounds alongside my mag tube, I have about 3" of space in the end of the tube for the srpig to compress.
As for how often it should be changed, it would depend on how often you use it and how you store your shotgun. The Nordic Components mag tube spring is $7.95 a piece on their website. Very quality stuff at a very good price. So I make it a point to replace my spring every year. It may be overkill, but I like dependabilty and maximum performance out of my shotgun everytime I use it.

+1 on the Nordic Components. They are a bunch of great guys there and quality products. And keep a couple handy.
An advice would be to remove the end cap of your magazine tube and let the spring relax and hang out the end. With the one end of the spring against the followed set on the receiver end, measure 14" of the spring from the end of the tube. 14" would give you a good tension when the spring is compressed with the end cap. Replace the end cap and see if you can fit the desired amount of rounds in the tube. If you find yourself almost being able to load that one last round, you may be able to cut a couple more coils off the spring. But remember that a compressed coil is only about 1/8 of an inch compared to a relaxed coil whcih could be as much as an inch apart. I would not recommend going below 12" as you'll loose to much coils.

A standard Mossberg 590 has a 20" barrel and the 8-round mag tube is flushed with the barrel. With your 18" barrel, you would be looking at extending the magazine tube about 2" past the barrel.
But one thing to consider is the rules of the 3-gun matches, with most allowing for 9 rounds in the gun at the start. The rules will vary on whether or not your 9th round can be in the chamber or in the tube. But since you're already getting a tube that extends past the barrel, consider getting one just a little more longer to allow for 9 rounds for a little bit of an advantage at the start.

What you want: http://www.jprifles.com/buy.php?item=JPFS-ALS
There are a variety of methods people use to mount this. Most use a clamp on rail out at the end of the barrel.
I highly recommend this Lyman Globe front sight. JP intoduced me to this sight and I don't regret it. It comes with a variety of inserts for you to choose from.
Here is another link with more info about it: http://www.jprifles.com/1.6.4.php

Does the 1x optic have better advantage than iron sights? Let’s take a look at them separately.
The challenge of iron sights is the proper alignment of two points (front and rear sights) to your target. It requires proper cheek weld, eye relief distance from the rear sight, and focusing on the sights to be able to shoot straight. The shooter have to be able to see the front sight through the rear sight regardless of the distance of the target. Focusing on the sights forces the shooter's vision to be narrower, forcing the shooter to widen his field of vision after engaging one target to start acquiring the next target. For the long distance, the shooter has to determine his hold-over.
The advantage of a 1x optic like the EoTech is the fast acquisition and aiming on the target as well as being able to shoot with both eyes open. Focus on the red dot is not as important as long as the shooter can see the dot on the target, allowing the shooter to have a wider field of vision and be more aware of his surroundings. A good cheek weld and proper eye relief is also not as important as long as the shooter can see your dot through the optic. And now EoTech and other companies offer these 1x optics with multiple dots or other reticles that compensate for bullet drop, so the shooter can use the proper dot for the distance instead of determining hold-overs. These are the reasons why law enforcement and the military like them.
I've run both a standard EoTech and back-up iron sights on my rifle when I was on SWAT. Both sights were set up for co-witness and both were zeroed for the same distance. I trained extensively with both as I will never rely on technology alone as they would sometimes fail. I know that with the EoTech, it's much faster to get on target than iron sights, especially if the targets are closer and bigger. It is also faster to acquire and engage multiple targets. For the long distance and smaller target, I can dim the dot enough to make it transparent and see the target behind the dot.
So does the 1x optic have better advantage than the iron sights? It clearly does, hence, the reason why law enforcement and the military like them. And depending on the 3-gun match which may have a lot more close-range targets than long distance (like Tri-Gun Challenge that is limited by the range facility), the standard one-dot 1x optics will have an advantage over the iron sights.
I understand that the Heavy Metal and Tactical Iron divisions need more competitors, and we want those new shooters who come with these 1x optics to feel welcome by not letting them get hosed in Tactical Optics. But right now, the only reason why the iron sights shooters are winning those divisions is that those shooters are seasoned competitors. I know that once these shooters switch to the 1x optic and start dominating the divisions with these 1x optics, it’ll be the death of iron sights. And once that happen, how are we going to make the new shooters who come with basic iron sights feel welcome?
-
I have to say that I'm disappointed with adding 1x optics to the Heavy Metal. One of the reasons I shoot HM is the challenge of the basic fundamentals of shooting and the heavy caliber. Alligning the front and rear sight to acquire the target and determining your hold-over is more challenging that putting a 1-point dot on the target. And now EoTech makes a 1x optic for the 308 with multiple dots to compensate for the bullet drop.
I just feel that HM and Tac Irons should be left alone to iron sights only as that is what makes them more challenging that the rest.

The best advice is to check the rules of the match concerning Heavy Metal. Some matches allow any .45ACP, others require a single stack gun. USPSA recently started allowing a Limited 10 legal gun, in .45 ACP only.
Very good advice. Some matches allow for only 8 rounds in the mags and some allow 10 rounds. Matches that allow only 8 rounds in the magazine would often times write "Single Stack Rule" but doesn't necessarily mean you have to use a Single Stack gun.
G21 is good to go at every major match on the circuit.
Superstition "used" to hold it to SS as did USPSA but both
now allow any 45.
My pistol of choice is the G21. Mods??? Sights (Dawson fixed), light weight connector from Lone Wolf,
grip tape (TruGrip) and a Seattle slug from Taylor Freelance.
I even game the hell out of my ammo choice....CCI Blazer 230 ball @ 190PF.
Patrick
Another good advice from the Heavy Metal's Champion. Patrick is definitely one to take advice from.

I have not kept up with the USPSA Multi-Gun Rules as most 3-Gun matches I shoot are "Out-Law" 3-Gun. Most of the "Out-Law" 3-Gun Rules do not say anything against it. It has been discussed a couple of times here in the forum and there were a lot of mixed feelings about its use. Until recently, I had been using a Mossberg 590 with a Knoxx Stock in the Heavy Metal Division. Rather than getting into a debate at the match, I made it a point to contact the Match Director of whatever match I was attending and asked specifically about the use of the Knoxx Stock in Heavy Metal. If they allowed it, I printed out their response and took it with me to the match incase an RO did not agree with it.
I've only been to a few big 3-Gun matches, but just to give you an idea on who says it’s allowed or not allowed:
Superstition Mountain Mystery 3-Gun: Allowed.
FN Midwest 3-Gun: NOT Allowed.
Ozark 3-Gun: Allowed.
DPMS Tri-Gun Challenge: Allowed.

I was able to roll the thing in 2 with 00 Buck at the Ozarks. I was very happy.
At some time in the future I hope to be able add some video, when I learn how. Jomar had the best run on the swinger. He was also shooting 00. First shot to the top, second to the bottom, It rocked horizontal. Then as it swung down he hit the bottom again bringing it to a complete stop. He stayed tough and punched it 2 more times to spin it.
Jay
By "best run", Jay meant that it was the most entertaining if not embarrassing run. We were using Federal 00 Buck with 9 pellets and the new flight control wad that makes the pattern tighter. I shot the top plate first with the belief that it would easier to acquire the bottom plate after the first swing. I shot the bottom plate with the second shot and it almost did a complete spin. When the bottom plate swung forward again, I had my head up my @ss and shot the bottom plate again instead of the top plate. The damn thing came to a complete dead stop. I went at it again but shot the bottom plate first and then the top plate and I had that thing spinning like crazy. Watching the video, it spun 4 (and almost 5) complete turns after I shot it.
I'm not a physics professor but I believe now that by shooting the bigger bottom plate first created a bigger momentum than shooting the smaller top plate first. Basically, putting force on the heavier plate first creates a bigger momentum than forcing the lighter plate first which has to move a heavier plate with it. I hope that makes sense.

I usually look in the GunBroker and GunsAmerica websites to get an idea how much a gun would be worth.

With a rifled barrel your pattern with birdshot will be about 6 feet wide at 10 yards... but your slugs should be accurate!
jj
One of our local guys showed up at a small 3-gun match with a newly-acquired shotgun and could not knock down a popper from 10 yards away. It turned out that he had a rifled barrel. I hope this M1 is really cheap as you will need a smooth bore barrel if you want to shoot 3-gun.
Another thing to note is that with the 18" barrell, the max you'll be able to load in the tube is either 4 or 6 shells depending on the set-up. You'll be doing a lot of reloads to be able to compete. If you put in an extension tube, it'll be longer than the 18" barrel.

I've been using a Mossberg 590 since I started shooting 3-gun about 5 years ago. I liked the 20" barrel and the 8 round tube it comes with. I didn't have any issues with it what-so-ever until this year when I went to the FN's Midwest 3-Gun. What I found is that I had a harder time knocking down a 4x4 steel plate at a longer distance. With the improved cylinder-only barrel, I couldn't make the pattern any tighter unless I run a #6 shot.
I just recently retired my Mossberg and bought a 24" Benelli Supernova. I have not used it in an actual match yet but just like diablodawg wrote, I like the versatility, the interchangeable chokes, longer barrel with a matching extended tube that holds 9 rounds easily, and the action is a lot more slicker.
And thanks to diablodawg's posting, I did find that I could line up two rounds in the port and load them both in the tube in one push. A big plus as the shotgun eats a lot of time to reload.

If you can wait, hold out for the JP. As a new JP / CTR02 shooter I can attest that I was 100% impressed with the functioning of the rifle. The smoothness of the action is incredible. All the components of this rifle make it a great package. It really has it all. You will not be dissapointed.
Jay
Jay and I got our JP rifles at the same time, but I went with the LRP-07 .308 as I shoot Heavy Metal. They run pretty much the same components, just different sizes. Just like how Jay described how impressed he was with the CTR-02, I am equally impressed with my LRP-07. The adjustable gas matched with the low-mass bolt and low-mass buffer makes the rifle well balanced. If you can wait, you will not be disappointed.
-
I'm interested and I know Jomar will jump at it.
Jay
I already started hopping just by reading this.
You can count on a few more guys from MPD Team to jump on board also.
Let us know what we could do to help.

A big thank you to Chad, Kirk, Damon, Sandra, all the match staff and RO's, and all the sponsors for a great match. It was our first time to Ozark 3-Gun and we had a great time. Our new 3-Gunner we brought along can't stop talking 3-Gun now. We will definitely be back next year and we'll bring along a few more guys.
This is the first 3-Gun match I've attended that ran smoothly ahead of time. All the stages were great and the professionalism of the RO's were outstanding. I wished things worked out better for Stage 9 as it was one of my better stages. The natural terrain setting and the design of the stages were awesome.
Special congratulations to Bryan Ray for taking 1st Place in Heavy Metal Division and for representing the Division well in the 3-Gun Nation Shoot-Off. I'm looking forward to our next meeting.
I am still curious about how well the 1x optic shooters faired against the iron sights shooters in Tactical Iron. I know 1st Place Kurt Miller and 2nd Place Jay Schmitt and some of the others are iron sights shooters, but I don't know who used 1x optics in the division.

I have the 16" Stainless Wilson-Nordic AR Rifle Barrel on an upper I put together. I am very happy with it. At 100 yds, I'm putting together 1/4 inch groups. I know 100 yards is not a good distance to judge the accuracy of a rifle, but I only use iron sights as I don't have a scope.

The match rules states, "11.4 Each division must have at least 10 (ten) competitors."
I'm planning on shooting in the Heavy Metal Division so I'm wondering if there is 10 competitors in that division yet. If not, does the Tactical Irons Divison have 10 competitors yet?
Ohhhhh no you don't Jomar! you ain't jumping divisions! are ya gettin skeered or sompin???
jj
JJ, what gives? I see you signed up for Open Division...are ya gettin skeered or sompin???
Jomar, I'm sure that is just one of the discrepancies that needs correction. JJ wouldn't PUNK you out like that. Right JJ.
Yall got that rite! Yer goin down, city kitty!!!
jj
Looking forward to seeing you try.

Villamor,
This is on the facebook page.
Registration will be at the Host Hotel Wed evening 6-8 and at the range Thurs 12-5. Thurs evening at Host Hotel 6:30-8:00. Look forward to seeing you all there.
If you go to page 14 there is a link to the facebook page. Otherwise I think you need an account to access it. Is it just two of you from your department for this match? I'm going solo this time.
Thanks for the info. I don't do Facebook so I haven't seen that info.
Jay Schmitt and I are coming and we're bringing a newbie along for his first big 3-Gun match.
Jomar

Is there a registration procedure for the match? If so, is it at the hotel or the range, and what time can you register in?
Also, are we going to be allowed to walk the stages on Thursday?
-
Any lengthy pistol shots? Like 30+ yards?
we cant give it all away! where's your sense of adventure?
It would help us with our "7 P's"...Proper Prior Planning Prevents Piss Poor Performance.
But I guess its better for me to have some surprises. That way, I'll have somewhat of an excuse in hand.
I can plan with the best of them......its just the execution that gets me............every time!
I do plan very well, having a solid Plan A with a backup Plan B before the start signal.
But when I hear the beep or when I have to take an extra shot or two, I almost always go direct to Plan Crap.

Very well said JJ.
As an iron sight shooter and engaging distant targets that may be low to the ground or in the shadow of the flasher, I found myself guesstimating about where the plate would be. I would love to see a black target with bright yellow backing. An idea would be a corrogated plastic panel painted in bright yellow behind the target. Those could take quite a few rounds and may not even need to be painted.
